My advice is for you to stick with stock rockers and get the trunion upgrade for them. Their available from Texas speed already done to them or you can buy the kit yourself and install the trunion upgrade yourself. There I think around 230?Maybe?...Also, make sure you measure your pushrod length with an adjustable pushrod length checker to be sure you still need 7.4.

All youll really gain with rockers is MAYBE 25 hp after another $400 tune and heavier valve train, i.e. worn out valve springs. Trunion upgrade and let her rip

I don't think adding roller rockers would add any horsepower, unless you dropped a couple grand or more on some Jesel Pro Steels.

If your heads have bronze valve guides, most aftermarket heads do, the wipe pattern on the valve tip from the rocker arm will wear out the guides. Roller rockers can be adjusted with shims to center the wipe pattern and make it narrow.

TSP heads use powder metal guides. keep the stock rockers,consider the trunnion bearing upgrade .no big power gain with full rollers ,maybe 5 hp.

when I said 25 hp i was for some reason thinking he was going from 1.7s to 1.85s. Idk why. I guess i read another post with that. but stock geometry is spot on. Its the safest bet unless youre getting into some serious stuff
